Description
FIELD OF THE INVENTION
[0001] The present invention is directed to a novel process for the preparation of compounds having inhibitory activity against sodium-dependent glucose transporter (SGLT) being present in the intestine or kidney.
BACKGROUND OF THE INVENTION
[0002] Diet therapy and exercise therapy are essential in the treatment of diabetes mellitus. When these therapies do not sufficiently control the conditions of patients, insulin or an oral antidiabetic agent is additionally used for the treatment of diabetes. At the present, there have been used as an antidiabetic agent biguanide compounds, sulfonylurea compounds, insulin resistance improving agents and a-glucosidase inhibitors. However, these antidiabetic agents have various side effects. For example, biguanide compounds cause lactic acidosis, sulfonylurea compounds cause significant hypoglycemia, insulin resistance improving agents cause edema and heart failure, and a-glucosidase inhibitors cause abdominal bloating and diarrhea. Under such circumstances, it has been desired to develop novel drugs for treatment of diabetes mellitus having no such side effects.
[0003] Recently, it has been reported that hyperglycemia participates in the onset and progressive impairment of diabetes mellitus, i.e., glucose toxicity theory. Namely, chronic hyperglycemia leads to decrease of insulin secretion and further to decrease of insulin sensitivity, and as a result, the blood glucose concentration is increased so that diabetes mellitus is self-exacerbated (UNGER, R.H., et al., "Hyperglycemia as an Inducer as well as a Consequence of Impaired Islet Cell Function and Insulin Resistance: Implications for the Management of Diabetes", Diabetologia, 1985, pp119-121, Vol. 28, Issue 3; ROSSETTI, L. et al., "Glucose Toxicity", Diabetes Care, 1990, pp 610-630, Vol. 13, Issue 6). Therefore, by treating hyperglycemia, the aforementioned self-exacerbating cycle is interrupted so that the prophylaxis or treatment of diabetes mellitus is made possible.
[0004] As one of the methods for treating hyperglycemia, it is considered to excrete an excess amount of glucose directly into urine so that the blood glucose concentration is normalized. For example, by inhibiting sodium-dependent glucose transporter being present at the proximal convoluted tubule of kidney, the re-absorption of glucose at the kidney is inhibited, by which the excretion of glucose into urine is promoted so that the blood glucose level is decreased. In fact, it is confirmed that by continuous subcutaneous administration of phlorizin having SGLT inhibitory activity to diabetic animal models, hyperglycemia is normalized and the blood glucose level thereof can be kept normal for a long time so that the insulin secretion and insulin resistance are improved (ROSSETTI, L., et al., "Correction of Hyperglycemia with Phlorizin Normalizes Tissue sensitivity to Insulin in Diabetic Rats", Journal of Clinical Investigation, 1987, pp 1510-1515, Vol. 79, Issue 5, pp. 1510-1515; ROSSETTI, L., et a., "EfFect of Chronic Hyperglycemia on in vivo Insulin Secretion in Partially Pancreatectomized Rats", Journal of Clinical Investigation, 1987, pp 1037-1044, Vol. 80, Issue 4; KAHN, B.B., et al., "Normalization of blood glucose in diabetic rats with phlorizin treatment reverses insulin-resistant glucose transport in adipose cells without restoring glucose transporter gene expression", J. Clin. Invest., 1991, pp 561-570, Vol. 87).
[0005] In addition, by treating diabetic animal models with SGLT inhibitory agents for a long time, insulin secretion response and insulin sensitivity of the animals are improved without incurring any adverse affects on the kidney or imbalance in blood levels of electrolytes, and as a result, the onset and progress of diabetic nephropathy and diabetic neuropathy are prevented (KENJI, T., et al., " Na+-Glucose Co-transporter (SGLT) Inhibitors as Antidiabetic Agents. 4. Synthesis and Pharmacological Properties of 4’-Dehydroxyphlorizin Derivatives Substituted on the B Ring", J. Med. Chem., 1999, pp 5311-5324, Vol. 42; KENJI, A., et al., "Improved diabetic syndrome in C57BL/KsJ-db/db mice by oral administration of the Na+-glucose cotransporter inhibitor T-1095", British Journal of Pharmacology, 2001, pp 578-586, Vol. 132, Issue 2; UETA, K., et al., "Long Term Treatment with the Na+ Glucose Co-transporter Inhibitor T-1095 causes Sustained Improvement in Hyperglycemia and Prevents Diabetic Neuropathy in Goto-Kakizaki Rats", Life Sei., 2005, pp 2655-2668, Vol. 76, Issue 23) [0006] From the above, SGLT inhibitors may be expected to improve insulin secretion and insulin resistance by decreasing the blood glucose level in diabetic patients and further prevent the onset and progress of diabetes mellitus and diabetic complications.

[0116] The present invention is directed to a process for the preparation of compounds of formula (I) as outlined in
Scheme 1, below.
Scheme 1 [0117] Accordingly, a suitably substituted compound of formula (V), wherein LG1 is a suitably selected leaving group such as bromo, iodo, and the like, preferably LG1 is bromooriodo, a known compound or compound prepared by known methods, is reacted with a mixture of a suitably selected zinc salt such as zinc dibromide (ZnBr2), zinc diiodide (Znl2), zinc ditriflate, and the like, preferably ZnBr2; or with an amine complex of zinc halide such as pyridine zinc bromide complex, N-methylmorpholine zinc bromide complex, and the like; wherein the zinc salt or amine complex of zinc halide is preferably present in an amount in the range of from about 0.33 to about 3.0 molar equivalents, more preferably in an amount in the range of from about 0.33 to about 1.0 molar equivalents, more preferably in an amount of about 0.5 molar equivalents; and a suitably selected organo-lithium reagent such as trimethylsilylmethyl lithium, n-hexyl lithium, sec-butyl lithium, n-butyl-lithium, t-butyllithium, methyl lithium, and the like, preferably n-hexyl lithium or n-butyl lithium; wherein the organo-lithium reagent is preferably present in an amount in the range of from about 0.5 to about 2.0 molar equivalents, preferably in an amount in the range of from about 1.0 to about 1.2 molar equivalents; in a suitably selected first hydrocarbon solvent, such as toluene, xylene, fluorobenzene, chlorobenzene, benzotrifluoride, and the like, preferably toluene; preferably at a temperature less than about room temperature, more preferably at a temperature in the range of from about-78°C to about room temperature; more preferably at about 0°C; to yield a mixture of the corresponding compound of formula (VI), wherein M1 is lithium and the zinc salt. Preferably, the compound of formula (VI) is not isolated.
[0118] In an embodiment of the present invention, the zinc salt is ZnBr2 and the organo-lithium reagent is n-butyl-lithium. In another embodiment of the present invention, the molar ratio of the zinc salt to the organo-lithium reagent is about 1:2. In another embodiment of the present invention, the zinc salt and the organo-lithium reagent are pre-mixed; preferably for a period of time in the range of from about 1 to about 2 hours.
[0119] It has been discovered that (a) pre-mixing of the zinc salt and organo-lithium reagent and (b) adding the compound of formula (V) to the pre-mixed zinc salt and organo-lithium reagent, improves the reaction conditions for making the compound of formula (VII). More particularly, the use of the pre-mixed zinc salt and organo-lithium reagent mixture permits forthe preparation of the compound of formula (VI) at a temperature of about 0°C. The higher temperature is preferred, particularly for large scale manufacture. Additionally, the use of the pre-mixed zinc salt and organo-lithium reagent mixture results in improved yield of the compound of formula (IX).
[0120] To the mixture of the compound of formula (VI) and the zinc salt is admixed a suitably selected first ether solvent such as diethyl ether, diisopropyl ether, di-n-butyl ether, MTBE, cyclopentylmethyl ether, and the like, preferably di-n-butyl ether or cyclopentyl methyl ether; wherein the first ether solvent is preferably present in an amount in the range of from about 5% to about 15% by volume (relative to the total volume of the first hydrocarbon solvent and the first ether solvent), or any amount or range therein; preferably in an amount in the range of from about 7% to about 10%, or any amount or range therein; more preferably, at about amount in the range of from about 8% to about 9%, or any amount or range therein; (to minimize the formation of undesired by-product, more particularly to minimize formation of the compound of formula (U)
(U)) to yield the corresponding compound of formula (VII), wherein M2 is a corresponding reactive zinc species, which compound is not isolated.
[0121] It is theorized that, when the zinc salt used in the previous reaction step is ZnBr2, then in the compound of formula (VII), M2 may include ZnBr; when the zinc salt used in the previous reaction step may include Znl2, then in the compound of formula (VII), M2 is Znl; when the zinc salt used in the previous reaction step is zinc ditriflate, then in the compound of formula (VII), M2 may include zinc triflate. At this time, the intermediate of formula (VII) has not been isolated or fully characterized (particularly, as to the identity of the M2 group).
[0122] It is further theorized that admixing the suitably selected first ether solvent with the mixture of the compound of formula (VI) and the zinc salt, preferably zinc bromide, results in chelation of the zinc salt. The chelated zinc bromide then reacts with the compound of formula (VI) to yield the corresponding compound of formula (VII).
[0123] The compound of formula (VII) is reacted with a suitably substituted compound of formula (VIII), wherein LG2 is a suitably selected leaving group such as bromo, chloro, iodo, and the like, preferably bromo; and wherein each Z is independently a suitably selected oxygen protecting group, for example Z may selected from the group consisting of benzyl, benzoyl, pivaloyl, isobutyryl, p-methoxy-benzyl, acetyl, propionyl, and the like, preferably, each Z protecting group is the same, more preferably each Z is pivaloyl, a known compound or compound prepared by known methods; wherein the compound of formula (VIII) is preferably present in an amount in the range of from about 0.5 to about 3.0 molar equivalents, or any amount or range therein, more preferably in an amount in the range of from about 0.8 to about 1.25 molar equivalents, or any amount or range therein, more preferably in an amount of about 1.0 to about 1.1 molar equivalents; optionally in a mixture of a suitably selected second ether solvent and a suitably selected second hydrocarbon solvent, wherein the second ether solvent is for example, diethyl ether, di-n-butyl ether, MTBE, 2-methyl-THF, di-isopropyl ether, cyclopentylmethyl ether, and the like, preferably di-n-butyl ether or cyclopentyl methyl ether; and wherein the second hydrocarbon solvent is for example toluene, xylene, fluorobenzene, chlorobenzene, benzotrifluoride, and the like, preferably toluene; (in an embodiment, the second ether solvent and the second hydrocarbon solvent are the same as the first ether solvent and the first hydrocarbon solvent, respectively); at a temperature in the range of from about room temperature to about reflux temperature, more preferably at a temperature in the range of from about 60°C to about 95°C; to yield the corresponding compound of formula (IX).
[0124] Preferably, the compound of formula (VIII), as a solution in a suitably selected second hydrocarbon solvent, more preferably a suitably selected second aromatic hydrocarbon, such as toluene, xylene, fluorobenzene, chlorobenzene, benzotrifluoride, and the like, more preferably, toluene; is added to a solution of the compound of formula (VII) in a suitably selected second ether solvent other than THF, such as diisopropyl ether, 1,4-dioxane, 2-methyl-THF, MTBE, cyclopentyl methyl ether (CPME), di-n-butyl ether, and the like, more preferably CPME or di-(n-butyl) ether, more preferably, di-(n-butyl) ether. Preferably, the final solvent mixture is present in a volume ratio of second ether solvent : second hydrocarbon solvent of from about 1: 1 to about 1:3.
[0125] The compound of formula (IX) is de-protected according to known methods, to yield the corresponding compound of formula (I). For example, wherein each Z is pivaloyl, the compound of formula (IX) may be de-protected by reacting with a suitably selected alkoxide or hydroxide base such as sodium methoxide, sodium ethoxide, lithium hydroxide, and the like, in a suitably selected solvent such as methanol, ethanol, and the like, to yield the corresponding compound of formula (I).
[0126] One skilled in the art will recognize that, depending on the particular protecting group Z, other reagents may be used in the de-protection step including, but not limited to, Pd/C, Pd(OH)2, PdCI2, Pd(OAc)2/Et3SiH, RaNi, a suitably selected acid, a suitably selected base, fluoride, and the like.
[0127] The compound of formula (I) is preferably isolated according to known methods, for example by extraction, filtration or column chromatography. The compound of formula (I) is further, preferably purified according to known methods, for example by recrystallization.
[0128] In an embodiment, the present invention is directed to a process for the preparation of a compound of formula (l-S), as outlined in Scheme 2, below.
Scheme 2 [0129] Accordingly, a suitably substituted compound offormula (V-S), wherein LG1 is a suitably selected leaving group such as bromo, iodo, and the like, preferably LG1 is bromooriodo, a known compound or compound prepared by known methods, is reacted with a mixture of a suitably selected zinc salt such as zinc dibromide (ZnBr2), zinc diiodide (Znl2), zinc ditriflate, and the like, preferably ZnBr2; or with an amine complex of zinc halide such as pyridine zinc bromide complex, N-methylmorpholine zinc bromide complex, and the like; wherein the zinc salt or amine complex of zinc halide is preferably present in an amount in the range of from about 0.33 to about 3.0 molar equivalents, more preferably in an amount in the range of from about 0.33 to about 1.0 molar equivalents, more preferably in an amount of about 0.5 molar equivalents; and a suitably selected organo-lithium reagent such as trimethylsilylmethyl lithium, n-hexyl lithium, sec-butyl lithium, n-butyl- lithium, t-butyllithium, methyl lithium, and the like, preferably n-hexyl lithium or n-butyl lithium; wherein the organo-lithium reagent is preferably present in an amount in the range of from about 0.5 to about 2.0 molar equivalents, preferably in an amount in the range of from about 1.0 to about 1.2 molar equivalents; in a suitably selected first hydrocarbon solvent, such as toluene, xylene, fluorobenzene, chlorobenzene, benzotrifluoride, and the like, preferably toluene; preferably at a temperature less than about room temperature, more preferably at a temperature in the range of from about -78°C to about room temperature; more preferably at about 0°C; to yield a mixture of the corresponding compound of formula (Vl-S), wherein M1 is lithium, and the zinc salt. Preferably, the compound of formula (Vl-S) is not isolated.
[0130] In an embodiment of the present invention, the zinc salt is ZnBr2 and the organo-lithium reagent is n-butyl-lithium. In another embodiment of the present invention, the molar ratio of the zinc salt to the organo-lithium reagent is about 1:2. In another embodiment of the present invention, the zinc salt and the organo-lithium reagent are pre-mixed; preferably for a period of time in the range of from about 1 to about 2 hours.
[0131] It has been discovered that (a) pre-mixing of the zinc salt and organo-lithium reagent and (b) adding the compound of formula (V-S) to the pre-mixed zinc salt and organo-lithium reagent, improves the reaction conditions for making the compound of formula (Vll-S). More particularly, the use of the pre-mixed zinc salt and organo-lithium reagent solution permits for the preparation of the compound of formula (Vl-S) at a temperature of about 0°C. The higher temperature is preferred, particularly for large scale manufacture. Additionally, the use of the pre-mixed zinc salt and organo-lithium reagent mixture results in improved yield of the compound of formula (IX-S).
[0132] To the mixture of the compound of formula (Vl-S) and the zinc salt is admixed a suitably selected first ether solvent such as diethyl ether, diisopropyl ether, di-n-butyl ether, MTBE, cyclopentylmethyl ether, and the like, preferably di-n-butyl ether or cyclopentyl methyl ether; wherein the first ether solvent is preferably present in an amount in the range of from about 5% to about 15% by volume (relative to the total volume of the first hydrocarbon solvent and the first ether solvent), or any amount or range therein; preferably in an amount in the range of from about 7% to about 10%, or any amount or range therein; more preferably, at about amount in the range of from about 8% to about 9%, or any amount or range therein; (to minimize the formation of undesired by-product, more particularly to minimize formation of the compound of formula (U-S)
(U-S), also known as 2-(4-fluorophenyl)-5-(2-methylbenzyl)thiophene); to yield the corresponding compound of formula (Vll-S), wherein M2 is a corresponding reactive zinc species, which compound is not isolated.
[0133] It is theorized that, when the zinc salt used in the previous reaction step is ZnBr2, then in the compound of formula (Vll-S), M2 may include ZnBr; when the zinc salt used in the previous reaction step is Znl2, then in the compound of formula (Vll-S), M2 may include Znl; when the zinc salt used in the previous reaction step is zinc ditriflate, then in the compound of formula (Vll-S), M2 may include zinc triflate. At this time, the intermediate of formula (VII) has not been isolated or fully characterized (particularly, as to the identity of the M2 group).
[0134] It is further theorized that admixing the suitably selected first ether solvent with the mixture of the compound of formula (Vl-S) and the zinc salt, preferably zinc bromide, results in chelation of the zinc salt. The chelated zinc bromide then reacts with the compound of formula (Vl-S) to yield the corresponding compound of formula (Vll-S).

[0136] Preferably, the compound of formula (Vlll-S), as a solution in a suitably selected second hydrocarbon solvent, more preferably a suitably selected second aromatic hydrocarbon, such as toluene, xylene, fluorobenzene, chlorobenzene, benzotrifluoride, and the like, more preferably, toluene; is added to a solution of the compound of formula (VII) in a suitably selected second ether solvent other than THF, such as diisopropyl ether, 1,4-dioxane, 2-methyl-THF, MTBE, cyclopentyl methyl ether (CPME), di-n-butyl ether, and the like, more preferably CPME ordi-(n-butyl) ether, more preferably di-(n-butyl) ether. Preferably, the final solvent mixture is present in a volume ratio of second ether solvent : second hydrocarbon solvent of from about 1:1 to about 1:3.
[0137] The compound of formula (IX-S) is de-protected according to known methods, to yield the corresponding compound offormula (l-S). For example, wherein each Z is pivaloyl, the compound of formula (IX-S) may be de-protected by reacting with a suitably selected alkoxide or hydroxide base such as sodium methoxide, sodium ethoxide, lithium hydroxide, and the like, in a suitably selected solvent such as methanol, ethanol, and the like, to yield the corresponding compound offormula (l-S).
[0138] One skilled in the art will recognize that, depending on the particular protecting group Z, other reagents may be used in the de-protection step including, but not limited to, Pd/C, Pd(OH)2, PdCI2, Pd(OAc)2/Et3SiH, RaNi, a suitably selected acid, a suitably selected base, fluoride, and the like.

Preferably, the compound of formula (Vl-K) is not isolated.
[0142] In an embodiment of the present invention, the zinc salt is ZnBr2 and the organo-lithium reagent is n-butyl-lithium. In another embodiment of the present invention, the molar ratio of the zinc salt to the organo-lithium reagent is about 1:2. In another embodiment of the present invention, the zinc salt and the organo-lithium reagent are pre-mixed; preferably for a period of time in the range of from about 1 to about 2 hours.
[0143] It has been discovered that (a) pre-mixing of the zinc salt and organo-lithium reagent and (b) adding the compound of formula (V-K) to the pre-mixed zinc salt and organo-lithium reagent, improves the reaction conditions for making the compound of formula (Vll-K). More particularly, the use of the pre-mixed zinc salt and organo-lithium reagent solution permits allows for the preparation of the compound of formula (Vl-K) at a temperature of about 0°C. The higher temperature is preferred, particularly for large scale manufacture. Additionally, the use of the pre-mixed zinc salt and organo-lithium reagent mixture results in improved yield of the compound of formula (IX-K).
[0144] To the mixture of the compound of formula (Vl-K) and the zinc salt is admixed a suitably selected first ether solvent such as diethyl ether, diisopropyl ether, di-n-butyl ether, MTBE, cyclopentylmethyl ether, and the like, preferably di-n-butyl ether or cyclopentyl methyl ether; wherein the first ether solvent is preferably present in an amount in the range of from about 5% to about 15% by volume (relative to the total volume of the first hydrocarbon solvent and the first ether solvent), or any amount or range therein; preferably in an amount in the range of from about 7% to about 10%, or any amount or range therein; more preferably, at about amount in the range of from about 8% to about 9%, or any amount or range therein; (to minimize the formation of undesired by-product, more particularly to minimize formation of the compound of formula (U-K)
(U-K), also known as 5-(5-(2-chlorobenzyl)thiophen-2-yl)-2-fluoropyridine); to yield the corresponding compound of formula (Vll-K), wherein M2 is a corresponding reactive zinc species, which compound is not isolated.
[0145] It is theorized that, when the zinc salt used in the previous reaction step is ZnBr2, then in the compound of formula (Vll-K), M2 may include ZnBr; when the zinc salt used in the previous reaction step is Znl2, then in the compound of formula (Vll-K), M2 may include Znl; when the zinc salt used in the previous reaction step is zinc ditriflate, then in the compound of formula (Vll-K), M2 may include zinc triflate. At this time, the intermediate of formula (Vll-K) has not been isolated or fully characterized (particularly, as to the identity of the M2 group).
[0146] It is further theorized that admixing the suitably selected first ether solvent with the mixture of the compound of formula (Vl-K) and the zinc salt, preferably zinc bromide, results in chelation of the zinc salt. The chelated zinc bromide then reacts with the compound of formula (Vl-K) to yield the corresponding compound of formula (Vll-K).
[0147] The compound of formula (Vll-K) is reacted with a suitably substituted compound of formula (Vlll-S), wherein LG2 is a suitably selected leaving group such as bromo, chloro, iodo, and the like, preferably bromo; and wherein each Z is independently a suitably selected oxygen protecting group, for example Z may selected from the group consisting of benzyl, benzoyl, pivaloyl, isobutyryl, p-methoxy-benzyl, acetyl, propionyl, and the like; preferably, each Z protecting group is the same, more preferably each Z is pivaloyl, a known compound or compound prepared by known methods; wherein the compound of formula (VIII) is preferably present in an amount in the range of from about 0.5 to about 3.0 molar equivalents, or any amount or range therein, more preferably in an amount in the range of from about 0.8 to about 1.25 molar equivalents, or any amount or range therein, more preferably in an amount of about 1.0 to about 1.1 molar equivalents; optionally in a mixture of a suitably selected second ether solvent and a suitably selected second hydrocarbon solvent, wherein the second ether solvent is for example, diethyl ether, di-n-butyl ether, MTBE, 2-Me-THF, cyclopentylmethyl ether, and the like, preferably di-n-butyl ether or cyclopentyl methyl ether; and wherein the second hydrocarbon solvent is for example toluene, xylene, fluorobenzene, chlorobenzene, benzotrifluoride, and the like, preferably toluene; (in an embodiment, the second ether solvent and the second hydrocarbon solvent are the same as the first ether solvent and the first hydrocarbon solvent, respectively); at a temperature in the range of from about room temperature to about reflux temperature, more preferably at a temperature in the range of from about 60°C to about 95°C; to yield the corresponding compound of formula (IX-K).
[0148] Preferably, the compound of formula (Vlll-S), as a solution in a suitably selected second hydrocarbon solvent, more preferably a suitably selected second aromatic hydrocarbon, such as toluene, xylene, fluorobenzene, chlorobenzene, benzotrifluoride, and the like, more preferably, toluene; is added to a solution of the compound of formula (Vll-K) in a suitably selected second ether solvent other than THF, such as diisopropyl ether, 1,4-dioxane, 2-methyl-THF, MTBE, cyclopentyl methyl ether (CPME), di-n-butyl ether, and the like, more preferably CPME ordi-(n-butyl) ether, more preferably di-(n-butyl) ether. Preferably, the final solvent mixture is present in a volume ratio of second ether solvent : second hydrocarbon solvent of from about 1:1 to about 1:3.

For example, wherein each Z is pivaloyl, the compound of formula (IX-K) may be de-protected by reacting with a suitably selected alkoxide or hydroxide base such as sodium methoxide, sodium ethoxide, lithium hydroxide, and the like, in a suitably selected solvent such as methanol, ethanol, and the like, to yield the corresponding compound of formula (l-K).
[0150] One skilled in the art will recognize that, depending on the particular protecting group Z, other reagents may be used in the de-protection step including, but not limited to, Pd/C, Pd(OH)2, PdCI2, Pd(OAc)2/Et3SiH, RaNi, a suitably selected acid, a suitably selected base, fluoride, and the like.
[0151] The compound of formula (l-K) is preferably isolated according to known methods, for example by extraction, filtration or column chromatography. The compound of formula (l-K) is further, preferably purified according to known methods, for example by recrystallization.
[0152] The present invention further comprises pharmaceutical compositions containing a compound prepared according to any of the processes described herein with a pharmaceutically acceptable carrier. Pharmaceutical compositions containing one or more of the compounds of the invention described herein as the active ingredient can be prepared by intimately mixing the compound or compounds with a pharmaceutical carrieraccording to conventional pharmaceutical compounding techniques. The carrier may take a wide variety of forms depending upon the desired route of administration (e.g., oral, parenteral). Thus for liquid oral preparations such as suspensions, elixirs and solutions, suitable carriers and additives include water, glycols, oils, alcohols, flavoring agents, preservatives, stabilizers, coloring agents and the like; for solid oral preparations, such as powders, capsules and tablets, suitable carriers and additives include starches, sugars, diluents, granulating agents, lubricants, binders, disintegrating agents and the like. Solid oral preparations may also be coated with substances such as sugars or be enteric-coated so as to modulate major site of absorption. For parenteral administration, the carrier will usually consist of sterile water and other ingredients may be added to increase solubility or preservation. Injectable suspensions or solutions may also be prepared utilizing aqueous carriers along with appropriate additives.
[0153] To prepare the pharmaceutical compositions of this invention, one or more compounds of the present invention as the active ingredient is intimately admixed with a pharmaceutical carrier according to conventional pharmaceutical compounding techniques, which carrier may take a wide variety of forms depending of the form of preparation desired for administration, e.g., oral or parenteral such as intramuscular. In preparing the compositions in oral dosage form, any of the usual pharmaceutical media may be employed. Thus, for liquid oral preparations, such as for example, suspensions, elixirs and solutions, suitable carriers and additives include water, glycols, oils, alcohols, flavoring agents, preservatives, coloring agents and the like; for solid oral preparations such as, for example, powders, capsules, caplets, gelcaps and tablets, suitable carriers and additives include starches, sugars, diluents, granulating agents, lubricants, binders, disintegrating agents and the like. Because of their ease in administration, tablets and capsules represent the most advantageous oral dosage unit form, in which case solid pharmaceutical carriers are obviously employed. If desired, tablets may be sugar coated or enteric coated by standard techniques. For parenterals, the carrier will usually comprise sterile water, through other ingredients, for example, for purposes such as aiding solubility or for preservation, may be included. Injectable suspensions may also be prepared, in which case appropriate liquid carriers, suspending agents and the like may be employed. The pharmaceutical compositions herein will contain, per dosage unit, e.g., tablet, capsule, powder, injection, teaspoonful and the like, an amount of the active ingredient necessary to deliver an effective dose as described above. The pharmaceutical compositions herein may contain, per unit dosage unit, e.g., tablet, capsule, powder, injection, suppository, teaspoonful and the like, of from about 0.01 to about 1,000 mg or any amount or range therein, and may be given at a dosage of from about 0.01 to about 300 mg/kg/day, or any amount or range therein, preferably from about 0.1 to about 50 mg/kg/day, or any amount or range therein. The dosages, however, may be varied depending upon the requirement of the patients, the severity of the condition being treated and the compound being employed. The use of either daily administration or post-periodic dosing may be employed.
[0154] Preferably these compositions are in unit dosage forms from such as tablets, pills, capsules, powders, granules, sterile parenteral solutions or suspensions, metered aerosol or liquid sprays, drops, ampoules, autoinjector devices or suppositories; for oral parenteral, intranasal, sublingual or rectal administration, or for administration by inhalation or insufflation. Alternatively, the composition may be presented in a form suitable for once-weekly or once-monthly administration; for example, an insoluble salt of the active compound, such as the decanoate salt, may be adapted to provide a depot preparation for intramuscular injection. For preparing solid compositions such as tablets, the principal active ingredient is mixed with a pharmaceutical carrier, e.g. conventional tableting ingredients such as corn starch, lactose, sucrose, sorbitol, talc, stearic acid, magnesium stearate, dicalcium phosphate or gums, and other pharmaceutical diluents, e.g. water, to form a solid preformulation composition containing a homogeneous mixture of a compound of the present invention, or a pharmaceutically acceptable salt thereof. When referring to these preformulation compositions as homogeneous, it is meant that the active ingredient is dispersed evenly throughout the composition so that the composition may be readily subdivided into equally effective dosage forms such as tablets, pills and capsules. This solid preformulation composition is then subdivided into unit dosage forms of the type described above containing from 0.1 to about 1,000 mg, or any amount or range therein, of the active ingredient of the present invention. The tablets or pills of the novel composition can be coated or otherwise compounded to provide a dosage form affording the advantage of prolonged action. For example, the tablet or pill can comprise an inner dosage and an outer dosage component, the latter being in the form of an envelope over the former. The two components can be separated by an enteric layer which serves to resist disintegration in the stomach and permits the inner component to pass intact into the duodenum or to be delayed in release. A variety of material can be used for such enteric layers or coatings, such materials including a number of polymeric acids with such materials as shellac, cetyl alcohol and cellulose acetate.
[0155] The liquid forms in which the novel compositions of the present invention may be incorporated for administration orally or by injection include, aqueous solutions, suitably flavoured syrups, aqueous or oil suspensions, and flavoured emulsions with edible oils such as cottonseed oil, sesame oil, coconut oil or peanut oil, as well as elixirs and similar pharmaceutical vehicles. Suitable dispersing or suspending agents for aqueous suspensions, include synthetic and natural gums such as tragacanth, acacia, alginate, dextran, sodium carboxymethylcellulose, methylcellulose, polyvinylpyrrolidone or gelatin.
[0156] The methods of treating described in the present invention may also be carried out using a pharmaceutical composition comprising any of the compounds as defined herein and a pharmaceutically acceptable carrier. The pharmaceutical composition may contain between about 0.01 mg and about 1000 mg of the compound, or any amount or range therein; preferably about 10 to about 500 mg of the compound, or any amount or range therein, and may be constituted into any form suitable for the mode of administration selected. Carriers include necessary and inert pharmaceutical excipients, including, but not limited to, binders, suspending agents, lubricants, flavorants, sweeteners, preservatives, dyes, and coatings. Compositions suitable for oral administration include solid forms, such as pills, tablets, caplets, capsules (each including immediate release, timed release and sustained release formulations), granules, and powders, and liquid forms, such as solutions, syrups, elixirs, emulsions, and suspensions. Forms useful for parenteral administration include sterile solutions, emulsions and suspensions.
[0157] Advantageously, compounds of the present invention may be administered in a single daily dose, or the total daily dosage may be administered in divided doses of two, three or four times daily. Furthermore, compounds for the present invention can be administered in intranasal form via topical use of suitable intranasal vehicles, or via transdermal skin patches well known to those of ordinary skill in that art. To be administered in the form of a transdermal delivery system, the dosage administration will, of course, be continuous rather than intermittent throughout the dosage regimen.
[0158] For instance, for oral administration in the form of a tablet or capsule, the active drug component can be combined with an oral, non-toxic pharmaceutically acceptable inert carrier such as ethanol, glycerol, water and the like. Moreover, when desired or necessary, suitable binders; lubricants, disintegrating agents and coloring agents can also be incorporated into the mixture. Suitable binders include, without limitation, starch, gelatin, natural sugars such as glucose or beta-lactose, corn sweeteners, natural and synthetic gums such as acacia, tragacanth or sodium oleate, sodium stearate, magnesium stearate, sodium benzoate, sodium acetate, sodium chloride and the like. Disintegrators include, without limitation, starch, methyl cellulose, agar, bentonite, xanthan gum and the like.
[0159] The liquid forms in suitably flavored suspending or dispersing agents such as the synthetic and natural gums, for example, tragacanth, acacia, methylcellulose and the like. For parenteral administration, sterile suspensions and solutions are desired. Isotonic preparations which generally contain suitable preservatives are employed when intravenous administration is desired.
[0160] To prepare a pharmaceutical composition of the present invention, a compound prepared according to any of the processes described herein as the active ingredient is intimately admixed with a pharmaceutical carrier according to conventional pharmaceutical compounding techniques, which carrier may take a wide variety of forms depending of the form of preparation desired for administration (e.g. oral or parenteral). Suitable pharmaceutically acceptable carriers are well known in the art. Descriptions of some of these pharmaceutically acceptable carriers may be found in The Handbook of Pharmaceutical Excipients, published by the American Pharmaceutical Association and the Pharmaceutical Society of Great Britain.
[0161] Methods of formulating pharmaceutical compositions have been described in numerous publications such as Pharmaceutical Dosage Forms: Tablets, Second Edition, Revised and Expanded, Volumes 1-3, edited by Lieberman et al; Pharmaceutical Dosage Forms: Parenteral Medications, Volumes 1-2, edited by Avis et al; and Pharmaceutical Dosage Forms: Disperse Systems, Volumes 1-2, edited by Lieberman etal; published by Marcel Dekker, Inc.
[0162] Compounds of this invention may be administered in any of the foregoing compositions and according to dosage regimens established in the art whenever treatment of disorders as described herein is required.
[0163] Optimal dosages to be administered may be readily determined by those skilled in the art, and will vary with the particular compound used, the mode of administration, the strength of the preparation, the mode of administration, and the advancement of the disease condition. In addition, factors associated with the particular patient being treated, including patient age, weight, diet and time of administration, will result in the need to adjust dosages.
[0164] One skilled in the art will recognize that, both in vivo and in vitro trials using suitable, known and generally accepted cell and / or animal models are predictive of the ability of a test compound to treat or prevent a given disorder.
[0165] One skilled in the art will further recognize that human clinical trails including first-in-human, dose ranging and efficacy trials, in healthy patients and / or those suffering from a given disorder, may be completed according to methods well known in the clinical and medical arts.
[0166] The following Examples are set forth to aid in the understanding of the invention, and are not intended and should not be construed to limit in any way the invention set forth in the claims which follow thereafter. In the Examples which follow, some synthesis products are listed as having been isolated as a residue. It will be understood by one of ordinary skill in the art that the term "residue" does not limit the physical state in which the product was isolated and may include, for example, a solid, an oil, a foam, a gum, a syrup, and the like.
Example 1 (2S,3S,4R,5R,6R)-2-(3-((5-(4-fluorophenyl)thiophen-2-yl)methyl)-4-methylphenyl)-6-(pivaloyloxymethyl) tetrahydro-2H-pyran-3,4,5-triyl tris(2,2-dimethylpropanoate) [0167]
[0168] In a 250mL RBF with mechanical stirrer, dried and under argon atmosphere, 2-(4-fluorophenyl)-5-(5-iodo-2-methylbenzyl)thiophene (22.20 mmoles; 9.06 g) was dissolved in a mixture of dried and degassed toluene (37.00 mL; 32.23 g) / diethyl ether (37.00 mL; 26.24 g) at room temperature. After cooling to -50°C (isopropanol + dry ice bath) under vigorous stirring, (trimethylsilyl)methyllithium (1 M in pentane, 37.00 mL) was added dropwise to the heterogeneous mixture. 30 min after the end of the addition, the conversion was checked by sampling and extra (trimethylsilyl)methyl-lithium was added if needed. After 15min., zinc dibromide (22.20 mmoles; 5.00 g) (solid extra dry from Aldrich) was added in one portion and the resulting mixture was allowed to warm up to 25°C over 1 hour. After 1 hour stirring at room temperature, diethyl ether and pentane were evaporated under reduced pressure (400mmHg) at 15°C. Finally a-D-glucopyranosyl bromide, 2,3,4,6-tetrakis(2,2-dimethyl propanoate) (10.72 g, 18.50 mmoles) dissolved in degassed toluene (18.50 mL) was added dropwise over 10 min and the resulting mixture was heated at 75°C for 21 hours. After cooling to room temperature, aqueous solution of ammonium chloride (1M, 100 mL) and ethyl acetate (150 mL) were added. After 10 min. stirring, the 2 phases were separated and the organic layer was washed twice with water (100 mL) and once with brine (100mL). The organic layerwas thereafter dried over sodium sulfate and the solvent was evaporated under reduced pressure to yield a clear brown oil. The oil was purified by MPLC (cartridge: 330g Si02, solvent system : 95/5 to 85/15 heptane/AcOEt) to yield the title compound, (2S,3S,4R,5R,6R)-2-(3-((5-(4-fluorophenyl)thiophen-2-yl)me-thyl)-4-methylphenyl)-6-(pivaloyloxymethyl) tetrahydro-2H-pyran-3,4,5-triyl tris(2,2-dimethylpropanoate) as a single isomer. The 1H NMR spectrum was consistent with the previously measured 1H NMR spectra for the title compound.

[0170] Ina 25mL Schlenk reactor, dried and under argon atmosphere, 2-(4-fluorophenyl)-5-(5-iodo-2-methylbenzyl)thi-ophene (1.99 mmoles; 813.71 mg) was dissolved in dry cyclopentylmethyl ether (CPME) (7.2 mL) at room temperature. After cooling to -50°C (acetonitrile + dry ice) under vigorous stirring, n-hexyllithium (2.3M in hexane, 966.31 μί) was added dropwise to the mixture.
